Model 28
The Model 28 can be used in many different measurement applications, and
with numerous types of equipment. Therefore all installations will be a little
different and it is the responsibility of the user to choose the bolts, screws, or
other mounting hardware that provides a quality installation and optimum
operation in their application.
Determine an appropriate mounting location and position for DigiScale in
your measuring application. Most installations of the Model 28 will hold the
scale stationary as the encoder moves along it during measurement.
However, the DigiScale will also operate correctly if the scale is moved
through the encoder during measurements; however this type of installation
is not recommended for the Model 28.
Note: Never drill through the colored portion of the scale at any point over
which the encoder will travel.
When installing the Model 28 you should use the Guide Clip to capture the
encoder movement along the scale (see illustrations).
1. Attach the scale to a fixed point in your application
using the included screws. Be sure the screw heads
do not protrude above the surface of the extrusion.
Place the encoder on the scale. Attach the guide clip
to a moving point in your application such that the
slot on the underside of the clip engages the post on
the top of the encoder and captures its movement
along the scale. The guide clip should exert some
pressure on the encoder over the full range of travel
as the two move as a single unit. Be sure the scale
and encoder are properly aligned as the encoder is
